Detailsinfo

A vulnerability classified as critical was found in RSA Authentication Agent for Web up to 5.3 on IIS. This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a heap-based overflow vulnerability. The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in RSA SecurID Web Agent 5, 5.2, and 5.3 allows remote attackers to execute arbitrary code via crafted chunked-encoding data.

The bug was discovered 02/29/2004. The weakness was presented 05/09/2005 by Gary O'leary-Steele with Sec-1 (Website). The advisory is shared for download at marc.theaimsgroup.com. This vulnerability was named CVE-2005-1471 since 05/06/2005. The attack can be initiated remotely. No form of authentication is required for a successful exploitation.
